--------------------------------------------------------------

It basically creates a new object and set the properties. Even use reflection, we still need
create a new object and set all the properties. also if we add new implementation of Row,
using reflection will not cover the new implementation class.

The wrapper only affects old API

> Since the latest Cql pagination is done and it should be more efficient, so we need update
CqlPagingRecordReader to use it instead of the custom thrift paging.
